     File: BezierView.h

 Abstract: BezierView implements a view with a single bezier path.  The path is created 

 using various constructs to demonstrate some different methods of creating bezier

 paths.  The color of the background and path element can be customized. In addition, 

 the line and cap style can be selected.  An example of the -setLineDash:count:phase: 

 method is included.   

 The application also includes a zoom feature that can be used to better view the 

 different line and fill styles.
